Can someone please be nice enough to help me out with my computer networking assignment homework?

Question

The question in my textbook goes as follows:
You work as a guard in a tower in a compound in Iraq for the US military and the only thing you have to communicate with your division’s building guard across town is two very powerful flashlights that can be signaled on and off. Imagine that you and your counterpart are tasked with meeting today and working out a way to send each other messages with flashing lights and that it is imperative that you communicate any danger at your location. Unfortunately neither of you remembers Morse code but you must work out a series of messages and a model for how you will communicate.

Describe the steps you should take to create the model for your communications. Be sure to break down the different steps that you will take and how the communications will be decoded at the other end. How many types of messages might there be. How will the model help your communications?
Any and all help is greatly appreciated! Thanks in advance!

Answer 1

You might use 2 models



--General alphabetic (ASCII, Morse code type)

--Specific, message-group (1="We are being attacked", 2="All's well", 3="I see a lot of sand"...)



Each has its advantages. If you only have a few possible messages, one byte would cover any possibility: however, such a model is inflexible. You'd need to think out any possibilities in advance.



What else? You'll have to build into your protocols the following--

-- Getting the other person's attention ("Open communications")

-- Allowing for miscommunication

-- Allowing for repeat requests

-- Some sort of notification that your message has been completed

Answer 2

How do you know that she copies the answers word for word? At first I suspected that she did it right in front of you. Then I read this, "She denies or ignores" it. How could she deny it if she's doing it right in front of you? Obviously it's not the fact that you are watching her do it. Chances are, if she has a 96, then she's been doing good on the tests; probably she knows the material well enough that she doesn't have to do the homework like the rest of the class that has to learn the material by doing homework. It's probably a lot quicker for her to copy than to think and work out the answer. OR it could be the case that she cheats on her exams as well. What you do: Ask her, "This Class Material is really hard, Hey, do you think that maybe you can give me a hand with this? PLEASE?!?!? " If she can help you proficiently, then she's probably not cheating. If She can't, if she's too busy, for whatever reason, then this gives you the opportunity to continue your investigation. When you do confront her, and when she admits it, tell her "My goal wasn't to attack you, but to make things more fair for ME (and the rest of the class) and to guide you into a more honest lifestyle" "It's not up to me to judge you, but you are my super close friend, I heard that college gets really hard, the answer just isn't around the corner, it's in your book, and you'll be forced to think about it" "I want you to learn, not to cheat" "If you're still going to cheat, then let's be friends, still, because I'm not going to lose you for something like this, I just thought maybe since we were super close, that you would AT LEAST admit to ME, that you are cheating"

Answer 3

Well, if you know any sign language you could use shadows created by the flashlight and your hand signals on a wall of the guard tower. The thumbs up or down is pretty universal.
